As promised earlier this fall, AT&T has announced via its Facebook page today that it will begin selling two new Windows Phone 7.5 based smartphones from Samsung on November 6. The budget conscious can check out the Samsung Focus Flash for $49.99 while the more feature rich Focus S will be sold for $199.99 (both naturally with a new two year contract).

The two new phones will join the HTC Radar as being among the first smartphones that will natively run the latest version of Microsoft's mobile operating system. T-Mobile is scheduled to sell the HTC Radar here in the US on November 2 for $99.99. AT&T is also scheduled to release the big HTC Titan (reviewed here at Neowin) at some point but there's no word on when that smartphone will be available.

With at least three new Windows Phone 7.5 device scheduled to be released in next couple of weeks, we should soon see if these new smartphones will be able to take a significant market share away from the super hot iPhone 4S along with the new Android-based phones such as the Droid Razer and the Android 4.0-powered Galaxy Nexus.
